Keywords:crosspoint switch? output buffers? switch matrices?

Analog Devices presents two 8 x 8 analog crosspoint switch matrices the ADV3228/ADV3229 that offer a ?3dB signal bandwidth of 750MHz and a slew rate of 2500 V/?s. The ADV3228 has a gain of +1, the ADV3229 has a gain of +2, and they both operate on voltage supplies of 5 V.

The ADV3228/ADV3229 include eight independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs to prevent off channels from loading the output bus. Channel switching is performed via a serial digital control that can accommodate daisy chaining of several devices or via a parallel control to allow updating of an individual output without reprogramming the entire array.

The ADV3228/ADV3229 are available in the 72-lead LFCSP package over the extended industrial temperature range of ?40C to +85C.

They are suitable for routing of high speed signals including Video (NTSC, PAL, S, SECAM, YUV, RGB), Compressed video (MPEG, wavelet), 3-level digital video (HDB3), data communications and telecommunications.
